Feature request: tooltip

[Paul Kocsis]

This may sound simple, and if there's a way to do it already, then I
apologize for labeling this as a "feature request"...but...for my
application it would be quite useful if a tooltip could display in something
other than a single line.  I'd like to be able to populate a tooltip with
several lines (lines separated by lineFeed characters) and have the tooltip
pop up as a small rectangular window instead of one looooong line :)
